Wood Gas as Engine Fuel
- Summary. Diesels can run char gas if spark plugs are added, or it can run on up to 90% gas if diesel is left to spark the mixture upon compression. Wood and char gas appears to work similarly. Missing link is flowable charcoal, which can be used as easily flowable fuel. Report is bullshit, claiming that wood gas operation is completely messy. Not true if char gas is used with flowable fuel, in which case ignition and fueling are comparable to liquid fuels by system design.
